As the nation marks the one-year anniversary of the Pulse Nightclub massacre in Orlando this week, a group of experts on active shooter/hostile incident response will assemble at National Fire Protection Association (NFPA) headquarters to develop NFPA 3000, Standard for Preparedness and Response to Active Shooter and/or Hostile Events. It is expected that the initial standard will be completed by early 2018; then the public will have the opportunity to offer input for immediate review.

Fire chiefs from France, the United Kingdom, and the United States gathered in Quincy, Massachusetts at the National Fire Protection Association (NFPA) Urban Fire Forum (UFF) to listen to first-hand accounts of some of the biggest emergency response incidents over the past 15 months, including hurricane response in Texas and Florida, the Grenfell Tower fire in London, and the Pulse Nightclub shooting in Orlando.

DDR5 DIMM Architectures The DDR5 generation of Double Data Rate DRAM memories has experienced rapid adoption in recent years. In particular, the JEDEC-defined DDR5 Dual Inline Memory Module (DIMM) cards have become a mainstay for systems looking for high-density, high-bandwidth, off-chip random access memory[1]. Within a short time, the DIMM architecture evolved from an interconnected hierarchy of only SDRAM memory devices (UDIMM[2]) to complex subsystems of interconnected components (RDIMM/LRDIMM/MRDIMM[3]). DIMM Designs and Popular Verification Use Cases The growing complexity of the DIMMs presented a challenge for pre-silicon verification engineers who could no longer simply validate against single DDR5 SDRAM memory models. They needed to consider how their designs would perform against DIMMs connected to each channel and operating at gigahertz clock speeds. To address this verification gap, Cadence developed DDR5 DIMM Memory Models that encapsulated all of the architectural complexities presented by real-world DIMMs based on a robust, easy-to-use, easy-to-debug, and easy-to-reconfigure methodology. This memory-subsystem-in-a-single-instance model has seen explosive adoption among the traditional IP Developer and SOC Integrator customers of Cadence Memory Models. The Cadence DIMM models act as a single unit with all of the relevant DIMM components instantiated and interconnected within, and with all AC/Timing parameters among the various components fully matched out-of-the-box, based on JEDEC specifications as well as datasheets of actual devices in the market. The typical use-case for the DIMM models has been where the DUT is a DDR5 Memory Controller + PHY IP stack, and the validation plan mandated compliance with the JEDEC standards and Memory Device vendor datasheets. Unique Use Case for the DIMM Discrete Component Models Although the Cadence DIMM models have enjoyed tremendous proliferation because of their cohesive implementation and unified user API, the actual DIMM Models are built on top of powerful, flexible discrete component models, each of which was designed to stand on its own as a complete SystemVerilog UVM-based VIP. All of these discrete component models exist in the Cadence VIP Catalog as standalone VIPs, complete with their own protocol compliance checking capabilities and their own configuration mappings comprehensively modeling individual AC/Timing parameters. Because of this deliberate design decision, the Cadence DIMM Discrete Component Models can support a unique use-case scenario. Some users seek to develop IC Designs for the various DIMM components. Such users need verification environments that can model the individual components of a DIMM and allow them the option to replace one or another component with their Component Design IP. They can then validate that their component design is fully compatible with the rest of the components on the DIMM and meets the integrity of the overall DIMM compliance with JEDEC standards or Memory Vendor datasheets. The Cadence Memory VIP portfolio today includes various examples that demonstrate how customers can create DIMM “wrappers” by selecting from among the available DIMM discrete component models and “stitching” them together to build their own custom testbench around their specific Component Design IP. A Solution for Unique Component Scenarios The Cadence DDR5 DIMM Memory Models and DIMM Discrete Component Models can provide users with a flexible approach to validating their specific component designs with a fully populated pre-silicon environment. Augmented Verification Capabilities When the DIMM “wrapper” model is augmented with the Cadence DFI VIP[4] that can simulate an MC+PHY stack and offers a SystemVerilog UVM test API to the verification engineer, the overall testbench transforms into a formidable pre-silicon validation vehicle. The DFI VIP is designed as a combination of an independent DFI MC VIP and a DFI PHY VIP connected to each other via the DFI Standard Interface and capable of operating seamlessly as a single unit. It presents a UVM Sequence API to the user into the DFI MC VIP with the Memory Interface of the PHY VIP connected to the DIMM “wrapper” model. With this testbench in hand, the user can then fully take advantage of the UVM Sequence Library that comes with the DFI VIP to enable deep validation of their Component Design inside the DIMM “wrapper” model. Verification Capabilities Further Enhanced A possible further enhancement comes with the potential addition of an instance of the Cadence DIMM Memory Model in a Passive Monitor mode at the DRAM Memory Interface. The DIMM Passive Monitor consumes the same configuration describing the DIMM “wrapper” in the testbench, and thus can act as a reference model for the DIMM wrapper. If the DIMM Passive Monitor responds successfully to accesses from the DFI VIP, but the DIMM wrapper does not, then it exposes potential bugs in the DUT Components or in the settings of their AC/Timing parameters inside the DIMM wrapper. Debuggability, Interface Visibility, and Protocol Compliance One of the key benefits of the DIMM Discrete Component Models that become manifest, whether in terms of the unique use-case scenario described here, or when working with the wholly unified DDR5 DIMM Memory Models, is the increased debuggability of the protocol functionality. The intentional separation of the discrete components of a DIMM allows the user to have full visibility of the memory traffic at every datapath landmark within a DIMM structure. For example, in modeling an LRDIMM or MRDIMM, the interface between the RCD component and the SDRAM components, the interface between the RCD component and the DB components, and the interface between the SDRAM components and the DB components—all are visible and accessible to the user. The user has full access to dump the values and states of the wire interconnects at these interfaces to the waveform viewer and thus can observe and correlate the activity against any protocol violations flagged in the trace logs by any one or more of the DIMM Discrete Component Models. Access to these interfaces is freely available when using the DIMM Discrete Component Models. On the unified DDR5 DIMM Memory Models, a feature called Debug Ports enables the same level of visibility into the individual interconnects amidst the SDRAM components, RCD components, and DB components. When combined with the Waveform Debugger[5] capability that comes built-in with the VIPs and Memory Models offered by Cadence and used with the Cadence Verisium Debug[6] tool, the enhanced debuggability becomes a powerful platform. With these debug accesses enabled, the user can pull out transaction streams, chip state and bank state streams, mode register streams, and error message streams all right next to their RTL signals in the same Verisium Debug waveform viewer window to debug failures all in one place. The Verisium Debug tool also parses all of the log files to probe and extract messages into a fully integrated Smart Log in a tabbed window fully hyperlinked to the waveform viewer, all at your fingertips. A Solution for Every Scenario Cadence's DDR5 DIMM Memory Models and DIMM Discrete Component Models , partnered with the Cadence DFI VIP, can provide users with a robust and flexible approach to validating their designs thoroughly and effectively in pre-silicon verification environments ahead of tapeout commitments. The solution offers unparalleled latitude in debuggability when the Debug Ports and Waveform Debugger functions of the Memory Models are switched on and boosted with the use of the Cadence Verisium Debug tool.

Even though that perception is partly the creation of right-wing media, the Democrats surely need to hone their identity.

Tactile controls are back in vogue. Apple added two new buttons to the iPhone 16, home appliances like stoves and washing machines are returning to knobs, and several car manufacturers are reintroducing buttons and dials to dashboards and steering wheels.

With this “re-buttonization,” as The Wall Street Journal describes it, demand for Rachel Plotnick’s expertise has grown. Plotnick, an associate professor of cinema and media studies at Indiana University in Bloomington, is the leading expert on buttons and how people interact with them. She studies the relationship between technology and society with a focus on everyday or overlooked technologies, and wrote the 2018 book Power Button: A History of Pleasure, Panic, and the Politics of Pushing (The MIT Press). Now, companies are reaching out to her to help improve their tactile controls.

Rachel Plotnick on...

• Researching the history of buttons
• The renaissance of physical controls
• Working with companies on “re-buttoning”

You wrote a book a few years ago about the history of buttons. What inspired that book?

Rachel Plotnick: Around 2009, I noticed there was a lot of discourse in the news about the death of the button. This was a couple years after the first iPhone had come out, and a lot of people were saying that, as touchscreens were becoming more popular, eventually we weren’t going to have any more physical buttons to push. This started to happen across a range of devices like the Microsoft Kinect, and after films like Minority Report had come out in the early 2000s, everyone thought we were moving to this kind of gesture or speech interface. I was fascinated by this idea that an entire interface could die, and that led me down this big wormhole, to try to understand how we came to be a society that pushed buttons everywhere we went.

The more that I looked around, the more that I saw not only were we pressing digital buttons on social media and to order things from Amazon, but also to start our coffee makers and go up and down in elevators and operate our televisions. The pervasiveness of the button as a technology pitted against this idea of buttons disappearing seemed like such an interesting dichotomy to me. And so I wanted to understand an origin story, if I could come up with it, of where buttons came from.

What did you find in your research?

Plotnick: One of the biggest observations I made was that a lot of fears and fantasies around pushing buttons were the same 100 years ago as they are today. I expected to see this society that wildly transformed and used buttons in such a different way, but I saw these persistent anxieties over time about control and who gets to push the button, and also these pleasures around button pushing that we can use for advertising and to make technology simpler. That pendulum swing between fantasy and fear, pleasure and panic, and how those themes persisted over more than a century was what really interested me. I liked seeing the connections between the past and the present.

We’ve experienced the rise of touchscreens, but now we might be seeing another shift—a renaissance in buttons and physical controls. What’s prompting the trend?

Plotnick: There was this kind of touchscreen mania, where all of a sudden everything became a touchscreen. Your car was a touchscreen, your refrigerator was a touchscreen. Over time, people became somewhat fatigued with that. That’s not to say touchscreens aren’t a really useful interface, I think they are. But on the other hand, people seem to have a hunger for physical buttons, both because you don’t always have to look at them—you can feel your way around for them when you don’t want to directly pay attention to them—but also because they offer a greater range of tactility and feedback.

If you look at gamers playing video games, they want to push a lot of buttons on those controls. And if you look at DJs and digital musicians, they have endless amounts of buttons and joysticks and dials to make music. There seems to be this kind of richness of the tactile experience that’s afforded by pushing buttons. They’re not perfect for every situation, but I think increasingly, we’re realizing the merit that the interface offers.

What else is motivating the re-buttoning of consumer devices?

Plotnick: Maybe screen fatigue. We spend all our days and nights on these devices, scrolling or constantly flipping through pages and videos, and there’s something tiring about that. The button may be a way to almost de-technologize our everyday existence, to a certain extent. That’s not to say buttons don’t work with screens very nicely—they’re often partners. But in a way, it’s taking away the priority of vision as a sense, and recognizing that a screen isn’t always the best way to interact with something.

When I’m driving, it’s actually unsafe for my car to be operated in that way. It’s hard to generalize and say, buttons are always easy and good, and touchscreens are difficult and bad, or vice versa. Buttons tend to offer you a really limited range of possibilities in terms of what you can do. Maybe that simplicity of limiting our field of choices offers more safety in certain situations.

It also seems like there’s an accessibility issue when prioritizing vision in device interfaces, right?

Plotnick: The blind community had to fight for years to make touchscreens more accessible. It’s always been funny to me that we call them touchscreens. We think about them as a touch modality, but a touchscreen prioritizes the visual. Over the last few years, we’re seeing Alexa and Siri and a lot of these other voice-activated systems that are making things a little bit more auditory as a way to deal with that. But the touchscreen is oriented around visuality.

It sounds like, in general, having multiple interface options is the best way to move forward—not that touchscreens are going to become completely passé, just like the button never actually died.

Plotnick: I think that’s accurate. We see paradigm shifts over time with technologies, but for the most part, we often recycle old ideas. It’s striking that if we look at the 1800s, people were sending messages via telegraph about what the future would look like if we all had this dashboard of buttons at our command where we could communicate with anyone and shop for anything. And that’s essentially what our smartphones became. We still have this dashboard menu approach. I think it means carefully considering what the right interface is for each situation.

Several companies have reached out to you to learn from your expertise. What do they want to know?

Plotnick: I think there is a hunger out there from companies designing buttons or consumer technologies to try to understand the history of how we used to do things, how we might bring that to bear on the present, and what the future looks like with these interfaces. I’ve had a number of interesting discussions with companies, including one that manufactures push-button interfaces. I had a conversation with them about medical devices like CT machines and X-ray machines, trying to imagine the easiest way to push a button in that situation, to save people time and improve the patient encounter.

I’ve also talked to people about what will make someone use a defibrillator or not. Even though it’s really simple to go up to these automatic machines, if you see someone going into cardiac arrest in a mall or out on the street, a lot of people are terrified to actually push the button that would get this machine started. We had a really fascinating discussion about why someone wouldn’t push a button, and what would it take to get them to feel okay about doing that.

In all of these cases, these are design questions, but they’re also social and cultural questions. I like the idea that people who are in the humanities studying these things from a long-term perspective can also speak to engineers trying to build these devices.

So these companies also want to know about the history of buttons?

Plotnick: I’ve had some fascinating conversations around history. We all want to learn what mistakes not to make and what worked well in the past. There’s often this narrative of progress, that things are only getting better with technology over time. But if we look at these lessons, I think we can see that sometimes things were simpler or better in a past moment, and sometimes they were harder. Often with new technologies, we think we’re completely reinventing the wheel. But maybe these concepts existed a long time ago, and we haven’t paid attention to that. There’s a lot to be learned from the past.
